Members of the iMore nation started hitting AT&T yesterday, the moment the previously announced official unlocks for iPhone became available, and so far the results have been successful but mixed. Forum member Irish Rose reports a successful iPhone 4 unlock, tested and working on T-Mobile EDGE. Reader Juan Tarrio, however, was told his iPhone 3GS and iPhone 3G unlocks would require approval and that he'd hear back by April 16.

Once AT&T has entered your iPhone IMEI number into Apple's database, you'll receive the following email confirmation:

We have reviewed your request and determined you are eligible to have the requested iPhone unlocked.

To complete the unlock simply:

Open iTunes on your Mac or PC and verify that you have internet connectivity

Connect your iPhone using the dock connector to USB cable that came with your iPhone

Backup and restore your iPhone using iTunes

Note: Since the unlock process requires your iPhone be restored via iTunes, that means it will remove any jailbreak currently on the device. If you were only jailbroken in order to be unlocked, that won't matter and you can go ahead and restore to your heart's content. If you have an iPhone 4S and have been holding back on iOS 5.1 until a nicely packaged, untethered jailbreak is released, you may want to hold off on restoring, or do without your jailbreak for a while.

Did you get a case number for your request? Because I got one and they said to wait until the 16th. Just wondering if those who didn't get case number receive an almost immediate unlock. I think I got a number because my phone was bought off contract.

I have the same situation - I have bought 2 at&t locked iphones 4 from ebay that I'm using outside US with GEVEY. I have just called AT&T customer support and told the IMEI numbers. After ~10 min of waiting they refused to unlock, because of the "security policy" constraints. Has anyone succeeded with unlock outside US?

I called yesterday and the representative took all my information, at the end provided me with a Case ID for further reference. They said that I had to wait until April 16th, the latest to see a response from AT&T. So, I'm gotta have to be patient. I'll post a comment when I hear from them.

I don't understand why the phone must be restored. I unlocked my iPhone 4 last week in Spain with the movistar carrier and I was simply told to put in a SIM card belonging to a different carrier and connect to iTunes.
When I put in the card, a popup appeared asking me whether to authenticate the phone using iTunes or using a WiFi connection. I selected my WiFi connection, and a couple of seconds later, the phone was connected to the new carrier.

I tried to unlock my iphone 3GS today morning. I got to Tech support and the person told me that my IMEI # does not allow upgrade in their system.
But when talking to find reason, my phone call disconnected.
Called again got different person and they transferred me and I gave my IMEI # and they were able to enter to system and push to APPLE. After 2 hrs I restored my iphone 3GS and I got message saying "Iphone Unlocked".
So I am good to go.

Could anybody help me? I'm from Uk and don't have AT&T account (obviously). As a single account can unlock 5 iPhones a year, could anyone with AT&T account help me unlock my iPhone? If so, please email me at: karolisk[at]rocketmail[dot]com . Of course, I would pay.

One call to AT&T customer service and I had my unlock processed no questions asked. Took 3 minutes to get the email.
I did backup and restore, but I didn't bother to check if I actually needed to. This is my backup 3GS which will be going to Straight Talk for the GF.

So are people doing this to their old iphones, for example my 3gs and 4 that I have sitting that I have planned to sell but havent. They are no longer the contract iphone on my account, my 4gs is, but my account is still under contract for a year and a half. Are those phones considered off contract even though im on contract?

Submitted my claim on April 9th and was told to fax a cover letter to a unlock dept for AT&T and then fax the original receipt with it..l was given an expected date of April 17 and it unlocked in less then 48 hours

I am untethered On 5.0.1 with my iPhone 4s so I won't restore to see if the unlock was sent but my case was supposed to be done by April 17th and I called on the 18th and they said the case was still open but no one has emailed or contacted me. Any advice?

Awesome tip, I was looking for some way to skip the restore, redsn0w didn't do it for me because I had installed ultrasn0w and sampref, as soon as I uninstalled them it got deactivated and Itunes did the rest

I'm now not sure the place you're getting your info, but good topic. I needs to spend a while finding out much more or understanding more. Thanks for wonderful info I used to be in search of this info for my mission.

After the factory unlock, are Tmobile users able to see push notifications, use iMessage, or Facetime? I am awaiting an unlock email, but am fearful that I won't be able to use push notifications the most. Can someone verify that we are able to use those features?
Thanks!

I do not even know the way I stopped up right here, but I assumed this put up used to be great. I do not recognize who you are however certainly you're going to a well-known blogger when you aren't already. Cheers!

If you're trying to get your phone unlocked thru AT&T, be warned that it's not easy. They have a long list of criteria that you have to meet before they're willing to release the unlock to you. For instance, your account has to be in good standing, and you'll also have to be out of contract. And even then, they might reject you for whatever reason. If you're not an AT&T customer like me, tough luck. Took about a month of waiting before I was told I was denied. You will have to go through 3rd party vendors that offer factory unlocking service instead. If any of you need the service you can check out the site I used: http://globalunlockcodes.com. I can't vouch for other vendors as I've never used their service and hence, don't know if they're reliable, but using the site provided, I unlocked my iPhone 4s and iPhone 4 at $45 each (which isn't bad at all considering a lot of companies out there are charging over $100 for the same exact service). Both were officially done so the unlocks are permanent and I've never had any issues with restoring or updating the software. Hope this helps.
